The mother reports that over the past 6 months, her daughter has had frequent mood swings. Sometimes, she is irritable for several days and loses her temper easily. In between these episodes, she behaves “normal,” spends time with her friends, and participates in gymnastics training twice a week. The mother has also noticed that her daughter needs more time than usual to get ready for school. Sometimes, she puts on excessive make-up.
